If you happen to be in the vicinity, the annual Adams Avenue Roots and Folk Music Festival is this coming weekend, May 3 and 4, in San Diego's Normal Heights neighborhood. Lou Curtiss, who is, among other things, an archivist for the Smithsonian and who has a huge collection of historic recordings, books people from far and wide for this event each year. It is a street fair with music, basically, with a lot of song-swapping, guitar and banjo workshops, etc.
